Unfortunately, we don't have permission to share our test data. However, it is an industrial control system (ICS). Most of the traffic is MODBUS, although we expect to be deploying the detector on ICSs using DNP3 and IEC 61850. In addition to MODBUS, our test data also has some TDS and HTTP traffic, and of course, the usual network management traffic (DNS, ICMP, DHCP, etc.).
ICS traffic tends to be quite regular. Our goal is to develop a detector that can flag a conversation using an anomalous communication protocol.

Could you show a little more concretely how you’re running Bro? Ideally you could provide a pcap that shows what you’re seeing although I understand if you’re unable to do that.
